Kiana, the Herrscher of the End, was accidentally swallowed by a strange dimensional rift and randomly transported to the Collapsed Iron World. She later managed to return to her original world and finally understood the principles of the dimensional rift. Finally, she used the dimensional rift to freely travel to other worlds for adventure, saving other worlds for fun.

[Kiana: As the Herrscher of the End, isn't it easy for me to save the world?]

[Theresa: So why did you come back after seven or eight years? Go do your homework!]

[Kiana: Ouch, Auntie, please stop pulling my ears~]

【Kiana: Why are there so many isomorphs! 】

The worlds we go to are more diverse, including Mihoyo's Honkai Impact 3rd, Honkai Impact 3rd, Genshin Impact, and possibly Juequ 0 in the future.

Or inexplicably enter another world of national destiny, strange stories, immortal heroes, movies, anime, or games...

Let me paint a big picture here.
